Value in Optical Networking
Lay a Dynamic Optical Foundation from which you can…> Grow to any capacity> Rapidly allocate bandwidth to meet traffic demands> Efficiently carry any kind of service (SDH, Video, Metro Ethernet, Wavelength)
…While dramatically reducing transport network costs > Integrated TDM Switching to collapse optical ADM rings onto one platform> Integrated Layer 2 switching for efficient video transport and commercial services from
one platform> Put electronics only at the service end points
Telecommunications Congress – Andicom 200911 April 10, 2023
Dynamic Optical Networking
7100 Networks can be incrementally built span by span as traffic requires
Additional spans can be added one by one hitlessly when required
Turn up virtually any type of service across the network regardless of fiber topology with ZERO additional equipment required at intermediate nodes
• SONET Rings• Pt to Pt Circuits (2.5G, 10G, 40G)• Ethernet (RPR, VLAN)
Build A Dynamic Optical Foundation that Can Support Any Number of Nodes, Any Amount of Traffic, and Any Type of Service
Note: Slide Best Viewed in Presentation Mode
Networks can be incrementally built span by span as traffic requires
Additional spans can be added one by one hitlessly when required
Once the network is in place – new traffic can be turned up across the network simply by adding port cards at the end points
Turn up any type of service across the network regardless of fiber topology with ZERO additional equipment required at intermediate nodes
• SDH Rings• Pt to Pt Circuits (2.5G, 10G, 40G)• Ethernet (RPR, VLAN)
Telecommunications Congress – Andicom 200912 April 10, 2023
Why deploy DON from day one?
First cost of ADMs will provide lowest first cost, but> Growth is expensive and cumbersome! > Only grow by stacking rings> Doesn’t efficiently support the migration to packet networks
Start with the optical layer day one…> Build the network topology differently – match service demand not fiber map> Deploy electronics only at the end points> Add capacity at a much lower cost> Seamless expansion of optical layer to new offices further improves network economics> Support transport of all types of services (Ethernet, SDH, SAN, Video) > Efficiently support packet requirements with integrated switching
Dynamic Optical Networks are the most cost effective design

Layer 2 Switched Transport Network
STEP 1: Implement L2 Switched Network using
STEP 2: Use 10G L2 network to aggregate traffic and switch to appropriate destinations
Control broadcast traffic through VLANs and Virtual Switches
Reduces Core Router Ports by only paying for actual bandwidth required
Reduces the quantity of 10G transponders in DWDM equipment, particularly at the Core Layer
Create logical mesh without costly physical fiber connections
STEP 3: Optimize the Aggregation Network locations by pulling all traffic into the network:
CAPEX Equipment Fiber Construction Software
OPEX Installation Maintenance Provisioning Troubleshooting Power and Space
